When would a researcher decide to use the matched pairs design what would be the advantages of this design?
The primary advantage of the matched pairs design is to use experimental control to reduce one or more sources of error between the groups. One limitation of this design can be the availability of participants.
What is the difference between concurrent measures designs and repeated measures designs?
What is the difference between concurrent-measures designs and repeated-measures designs? Concurrent-measures designs expose participants to the levels of the independent variable at roughly the same time; repeated-measures designs expose participants to the levels of the independent variable sequentially.
Which of the following is an important advantage of a repeated measures study?
Which of the following is an important advantage of a repeated-measures study? Individual differences do not contribute to the analysis, thereby reducing unsystematic and unpredicted error.
What is F value in repeated measures Anova?
F stands for F-Ratio. This is the test statistic calculated by the ANOVA. You need to report the F-value for your variable, which can be found in the Word_List row. It is calculated by dividing the mean squares for the variable by its error mean squares.
What are the two main assumptions underlying the repeated measures t test?
The common assumptions made when doing a t-test include those regarding the scale of measurement, random sampling, normality of data distribution, adequacy of sample size, and equality of variance in standard deviation.
What is the advantage of a repeated measures research study quizlet?
What is the advantage of a repeated-subject research study? It uses exactly the same individuals in all treatment conditions. A smaller number of subjects is required. Why might a repeated-measures study require half the number of subjects compared to a similar matched-subjects study with the same number of scores?
What is the order of effect?
Order effects are where the order of treatments in an experiment matter. In other words, placing the treatments in a different order alter the results.
What is specific items effect?
specific item effects. the results of your study may be due to the materials you use and not the IV (materials→DV not IV→DV); could be a confounding variable.
What is meant by demand characteristics?
In a psychological experiment, a demand characteristic is a subtle cue that makes participants aware of what the experimenter expects to find or how participants are expected to behave.
